Installation and wiring 3-5
3-6. Other sensor systems
To connect other sensor systems, follow the general pattern of the terminal connections as listed below:
11 and 12 : Always used for temperature compensation resistor input.
13 and 17 : Used for the secondary ‘collector’ coil.
15 and 16 : Used for the primary ‘drive’ coil.

3-6-1. Sensor cable connections using junction box (BA10) and extension cable (WF10)
Where a convenient installation is not possible using the standard cables between sensors and transmit-
ter, a junction box and extension cable may be used. The Yokogawa BA10 junction box and the WF10
extension cable should be used. These items are manufactured to a very high standard and are neces-
sary to ensure that the specifications of the system are not compromised. The total cable length should
not exceed 60 mtr (e.g. 5 m fixed cable and 55 m extension cable).
